Your Complete Guide To Metal Roof Replacement

Posted on September 8, 2024

If you’ve been thinking about replacing your metal roof but aren’t sure where to start, don’t worry—you’re in the right place.

Choosing between sticking with metal or switching to another roofing material can feel overwhelming, but I’m here to walk you through it step by step.

In this guide, I’ll cover everything from the key signs that it’s time for a new roof to the installation process and costs. Plus, we’ll explore why metal roofs are such a smart, long-lasting choice.

Why Choose a Metal Roofing System?

When your roof starts to show signs of wear, you might wonder: why stick with metal instead of switching to shingles or something else?

Here’s the scoop—metal roofs last a long time. We’re talking 40 to 70 years, way longer than the 15 to 30 years you get from traditional shingles. They’re also tough enough to handle everything from heavy rain to snowstorms. On top of that, metal roofs are great at reflecting sunlight, which keeps your home cooler in the summer and can lower your energy bills.

Plus, if you’re looking for eco-friendly options, metal roofs are often made from recycled materials and can be fully recycled when it’s time to replace them.

Signs It’s Time For A Metal Roof Replacement

Even though metal roofs are durable, they don’t last forever. Wondering if it’s time to replace yours? Here are a few tell-tale signs:

Rust and Corrosion: If you see rust spots forming, it means your roof’s protective coating is wearing down.
Leaks or Water Damage: If you’re noticing leaks, it could be time for repair or a complete replacement.
Loose Panels or Missing Fasteners: If some of your panels are coming loose or missing fasteners altogether, your roof could be vulnerable to more serious problems.
Fading or Chalking: A faded color or chalky residue on the surface might not be a structural issue, but it can indicate that your roof’s protective finish is wearing thin.
More Noise During Rainstorms: If your roof suddenly seems noisier during bad weather, it could be a sign that the insulation or panels are no longer performing as they should.

Preparing For A Metal Roof Replacement

Are you ready to replace your roof? It’s not as hard as it sounds. Here’s how to prep for the job:

Inspect Your Roof: Start by checking your roof for the signs we just talked about. Take notes on any areas that look like they need extra attention.
Check the Roof Deck: The surface under your roof panels (the roof deck) should be in good shape. If you spot any signs of rot or mold, fix them before the new roof goes on.
Gather Tools and Materials: Even if you’re hiring a pro, it’s good to know what’s involved:
- Hammer, pry bar, and roofing shovel for removing old materials
- Power drill and metal snips for cutting and securing panels
- Safety gear like gloves and non-slip boots

How To Replace A Metal Roof (Step-by-Step)

Here’s how the process works, broken down into easy steps:

Remove the Old Roof

Start by removing the old roofing material—whether it’s metal, asphalt shingles, or something else. Use a roofing shovel or pry bar to carefully lift the panels and remove any nails or screws. Remember to recycle the old materials if possible.

Install Underlayment

Underlayment goes between the roof deck and the metal panels, acting as a moisture barrier. You’ve got two main options: synthetic metal roof underlayment (more durable but pricier) or felt paper (cheaper but doesn’t last as long).

Start at the bottom and work your way up.
Overlap each row by at least six inches to ensure there’s no room for water to seep through.
Secure it with a staple gun or nails.

Ensure Proper Ventilation

Before installing the metal panels, make sure your roof has proper ventilation. Good ventilation helps prevent moisture buildup, which can damage the roof deck and reduce the roof’s lifespan. You can achieve this with ridge vents, soffit vents, or other roof ventilation systems. Proper airflow keeps your attic cooler in summer and reduces condensation in winter.

Mount the New Metal Panels

Now for the exciting part! Start by aligning the first panel along the eaves. Make sure it’s perfectly straight—any misalignment here can cause leaks later on. For those opting for standing seam metal roof installation, carefully align each panel to avoid leaks.

Use screws with rubber washers to fasten the panels, spacing them about 12 inches apart.
Overlap each panel to make sure water flows off the roof properly.

Add Flashing

Flashing is the key to sealing off tricky areas like chimneys, vents, and skylights. Make sure it’s installed properly to prevent leaks.

Final Inspection and Cleanup

Before you’re done, inspect the roof for loose screws or gaps around vents and chimneys. Double-check that the panels are secure and aligned properly. Once everything looks good, clean up any leftover materials.

Practical Tips For A Smooth Installation

Here are a few tips to ensure your roof replacement goes off without a hitch:

Work with a Professional: DIY might sound tempting, but metal roof installation is best left to the pros. They have the right tools and know-how to get the job done right.
Check Local Building Codes: Make sure you’re following local regulations. This can help you avoid fines and ensure your roof meets safety standards.
Plan for the Weather: Metal roofs are best installed in dry conditions. Try to schedule your replacement when you’re not expecting rain or storms.

How Much Does It Cost to Replace a Metal Roof?

Let’s talk numbers—how much does metal roof replacement cost?

Materials: Steel and aluminum are usually more affordable, costing around $100 to $300 per 100 square feet. If you’re going for high-end copper, expect to pay upwards of $1,000 per 100 square feet.
Labor: Hiring a pro will run you $200 to $500 per 100 square feet, depending on the complexity of your roof and local labor costs.
Total Cost: For a 2,000-square-foot roof, you’re looking at $8,000 to $30,000, depending on the materials you choose.

While the upfront cost may be higher than asphalt shingles, metal roofs last longer and can help you save on energy bills.

How Long Does It Take To Replace A Metal Roof?

On average, a metal roof replacement on a standard residential home takes around 3 to 7 days. For larger or more intricate roofs, you should expect the project to take closer to a week or more. Here’s what influences the timeline:

Roof Size: A smaller roof may only take a few days, while larger or more complex roofs could take a week or more.
Weather Conditions: Bad weather like rain, wind, or snow can delay installation. Roofers usually prefer working in dry, mild conditions for safety and quality control.
Roof Complexity: The shape and style of your roof also play a role. If your roof has multiple angles, dormers, or chimneys, it may take longer to install metal panels and flashing.
Removal of Old Roofing: If your old roof needs to be removed, this adds time to the project. Removing multiple layers of old roofing material can take extra time and labor.
Material Type: The type of metal roof you choose also matters. Standing seam metal roofs may take a bit longer to install compared to metal shingles, as they require more precise installation.
Contractor Experience: An experienced roofing contractor will usually complete the job faster while ensuring quality work.

If you’re under a time crunch, you can always discuss the expected timeline with your contractor to plan accordingly.
